Thread: Performance Upgrades

Are you scanning your car? Running a 3.5 pulley with no supporting mods isnt the best idea.

Read this thread please so you get a basic understanding of things, dont go by what ZZP or Intense say.

And send that K&N CAI back and save yourself $200. Make this http://www.grandprixforums.net/simpl...res-33351.html

Get a way to scan it.

Read that thread.

Get some exhaust mods, that's the restriction.

Pulley drop should always be the last thing on the list of "mods".

get a aeroforce scan guage a little pricey but can save your ass 99pgpgt has one for sale acutally message him. also get a aem wideband for the air fuel ratio

Also scanning, not very familiar with that. Can i just get my mechanic buddy to scan it? lol

No; you want live feed scanner, like an Aeroforce gauge.

good move read read read that how you keep your car from breaking if you wanna mod it, i am just super curious though how did you come to the conclusion that a 3.5" pulley with give you 24hp?

ive seen that before too i wanna say 3800performance advertieses that

what company

send it back get a modular hub system pulley

ok because thats a very silly number a 3.4" pulley with give you 300~ HP at the crank if done right

a 3.4 setup will get you back to 240 whp

Stage kits: Junk.
What vendor sites tell you: Mostly lies about what needs to be ran for "X" pulley.

What every site SHOULD say is: Fix the crappy 3800 exhaust, make sure everything else is in good shape to mod, get a way to scan the car or a tuner, then start diving into crap.

Also note: You will break things, especially now that these cars are getting older.

Also also note: Stock GTP's will make about 195-205 WHP stock. Proper 3.4" setup cars will make about 230-240 WHP. Typical drivetrain loss is about 18-20% IIRC, so about 275-290 CHP.

But measuring to the crank is lame. Wheels is the only measurement that should matter.

i feel we just shat on this guys day. but its for the better and it will save him money in the long run

And NOW you get the meaning behind the Safely Modding thread.
